diesel fuel injector rebuild

[torsionbar]

Hello all, I have ~150k on my '98 E300 and I'd like to have the fuel injectors rebuilt with new nozzles, either Bosio or Monark. I can order the nozzles myself, but can anyone recommend a good Mercedes diesel shop to rebuild them?

I've got none near me, as far as I know, here in the Washington DC metro area. I can pack them up carefully and ship them wherever, just want a competent experienced shop to work on them, who will ultrasonic clean the parts, and pop-test and shim them to correct opening pressure.

I know it can be done DIY, but I don't own a pop-tester, an ultrasonic cleaner, or an injector shim collection, so I'd rather let a Pro handle it who has the proper equipment to do it right.

Thank you
